Detailed Description
The utility model is further described below. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in the figure, the cooling device of the film blowing machine comprises a cooling air ring which is used in a matched mode, the cooling air ring comprises an annular main body 1, an air inlet and an air outlet are formed in the annular main body 1, an air suction nozzle 2 is arranged on one side of the cooling air ring 1, the air suction nozzle 2 is connected with an air suction device 3, the air suction nozzle 2 comprises an annular cavity, an air opening 4 is formed in the cavity, one side of the air suction device 3 is connected with a cooling box 6 through a pipeline 5, and cooling liquid is filled in the cooling box 6.
When the cooling device is used, cooling air is blown to the film from the air outlet of the annular main body 1, is scattered around after cooling work is completed, is sucked away by the air suction nozzle 2, and enters the cooling box 6 through the pipeline 5 to be cooled, so that hot air of the surrounding environment is reduced.
Furthermore, a first partition plate 7 and a second partition plate 8 are arranged in the cooling box 6, the first partition plate 7 and the second partition plate 8 are arranged in a staggered mode, the first partition plate 7 is connected with the left side wall of the cooling box 6, and the second partition plate 8 is connected with the right side wall of the cooling box 6.
Through the first partition plate 7 and the second partition plate 8 which are arranged in a staggered mode, the time of hot air in the cooling box 6 is increased, and the cooling effect is better.
Further, the lengths of the first partition plate 7 and the second partition plate 8 are smaller than the width of the cooling tank 6, and the heights of the first partition plate 7 and the second partition plate 8 are the same as the height in the cooling tank 6. Ensuring the passage of the hot air from the channel formed by the first 7 and second 8 partitions. The height of the cooling liquid in the cooling tank 6 is approximately two thirds of the height of the cooling tank.
